[0002] Injection molded parts are plastic components manufactured through an injection molding process. A multi-cavity injection molded part refers to an injection molded part having two or more independent cavities or chambers. After the multi-cavity injection molded part is injection molded, an operator will place the multi-cavity injection molded part on a cooling table for natural cooling. During the natural cooling process of the multi-cavity injection molded part, the cooling speeds of the multiple chambers on the multi-cavity injection molded part cannot be kept consistent, which easily causes the shrinkage amount of some chambers to be larger, while the shrinkage amount of some other chambers to be smaller, resulting in a large difference between the size of the multi-cavity injection molded part after cooling and the designed size, and thus being not conducive to improving the qualified rate of the multi-cavity injection molded part.

[0038] Referring to Figures 1 to 4 , the injection molded part shaping device according to an embodiment of the present utility model includes:

[0039] Lower clamping plate 100;

[0040] Multiple shaping bumps 110 are all arranged on the lower clamping plate 100. The multiple shaping bumps 110 are respectively used to extend into multiple cavities of the multi-cavity injection molded part, so that the multiple shaping bumps 110 can respectively abut against the bottom walls of the multiple cavities of the multi-cavity injection molded part, and the multiple shaping bumps 110 can respectively limit the shrinkage deformation amounts of the multiple cavities of the multi-cavity injection molded part;

[0041] An upper clamping plate 200, one end of the upper clamping plate 200 is hinged to one end of the lower clamping plate 100, so that the upper clamping plate 200 can approach or move away from the lower clamping plate 100;

[0042] A locking assembly 400 is arranged on the other end of the upper clamping plate 200. The other end of the upper clamping plate 200 can be fixed to the other end of the lower clamping plate 100 through the locking assembly 400, so that the upper clamping plate 200 and the multiple shaping bumps 110 clamp the multi-cavity injection molded part.

[0043] It can be understood that after the multi-cavity injection molded part is formed in the mold, the operator can take out the multi-cavity injection molded part from the mold. Then the operator can respectively align the multiple cavities of the multi-cavity injection molded part with the multiple shaping bumps 110 on the lower clamping plate 100 and place the multi-cavity injection molded part on the lower clamping plate 100, and make the multiple shaping bumps 110 respectively extend into the multiple cavities of the multi-cavity injection molded part. At this time, the multiple shaping bumps 110 respectively abut against the bottom walls of the multiple cavities of the multi-cavity injection molded part, that is, the multiple shaping bumps 110 play a role in supporting the multi-cavity injection molded part. After the multi-cavity injection molded part is placed, the operator rotates the upper clamping plate 200 to make the upper clamping plate 200 approach the lower clamping plate 100. Then the operator controls the locking assembly 400, so that the other end of the upper clamping plate 200 can be fixed to the other end of the lower clamping plate 100 through the locking assembly 400. At this time, the upper clamping plate 200 and the multiple shaping bumps 110 are in a state of clamping the multi-cavity injection molded part, and the operator can place the injection molding part shaping device and the multi-cavity injection molded part on the cooling table for natural cooling.

[0044] Under the action of multiple shaping bumps 110, the multiple shaping bumps 110 can limit the space and direction of free contraction of multiple chambers on the multi-cavity injection molded part during the cooling process, limit the shrinkage deformation amount of the multiple chambers on the multi-cavity injection molded part, reduce the large difference in shrinkage amount caused by uneven shrinkage of the multiple chambers, and further reduce the difference between the size of the multi-cavity injection molded part after cooling and the designed size, which is conducive to improving the yield rate of the multi-cavity injection molded part. On the other hand, the upper clamping plate 200 and the multiple shaping bumps 110 can mechanically clamp the multi-cavity injection molded part, so that the shape of each part of the multi-cavity injection molded part is fixed in a predetermined state, and further the multi-cavity injection molded part after natural cooling will be closer to the designed shape, which is also conducive to improving the yield rate of the multi-cavity injection molded part. After the multi-cavity injection molded part is cooled, the operator controls the locking assembly 400 to loosen the upper clamping plate 200 from the multi-cavity injection molded part, and then the multi-cavity injection molded part can be taken away from the lower clamping plate 100.

[0045] It should be noted that in the present utility model, the multiple shaping bumps 110 can respectively limit the shrinkage deformation amount of multiple chambers on the multi-cavity injection molded part, that is, the shaping bumps 110 do not hinder the shrinkage deformation occurring on the multi-cavity injection molded part, but only limit the shrinkage deformation amount of the chambers, avoiding excessive shrinkage of the chambers to complete the shaping of the chambers.

[0046] It should be noted that referring to Figure 1 and Figure 2 , in the present utility model, there is not only multiple chambers on the multi-cavity injection molded part, but also a protruding part. Referring to Figure 4 , an avoidance groove 120 is formed on the lower clamping plate 100, and the avoidance groove 120 is used for the protruding part of the multi-cavity injection molded part to extend into. It can be understood that the avoidance groove 120 can allow the protruding part of the multi-cavity injection molded part to extend into, avoiding the interference of the protruding part of the multi-cavity injection molded part on the clamping of the multi-cavity injection molded part by the upper clamping plate 200 and the multiple shaping bumps 110.

[0047] In the embodiment of the present utility model, the operator can also put the injection molded part shaping device and the multi-cavity injection molded part into water for water cooling together to accelerate the cooling of the multi-cavity injection molded part, so that the operator can perform subsequent processing on the multi-cavity injection molded part faster.

[0048] Referring to Figure 4 and Figure 5, the injection molding part shaping device further includes a hinge 300. One blade of the hinge 300 is connected to one end of the upper clamping plate 200, and the other blade of the hinge 300 is connected to one end of the lower clamping plate 100, so that one end of the upper clamping plate 200 is hinged to one end of the lower clamping plate 100 through the hinge 300. It can be understood that the hinge 300 includes a pin shaft and two blades. The hinge 300 is a common component. One end of the upper clamping plate 200 and one end of the lower clamping plate 100 are connected through the hinge 300, so that one end of the upper clamping plate 200 can be hinged to one end of the lower clamping plate 100 through the hinge 300, and the upper clamping plate 200 can swing away from or close to the lower clamping plate 100.

[0049] Reference Figure 6 and Figure 7 , the locking assembly 400 includes an arc-shaped elastic piece 410. A buckle groove 130 is provided at the other end of the lower clamping plate 100. The upper end of the arc-shaped elastic piece 410 is hinged to the other end of the upper clamping plate 200. The lower end of the arc-shaped elastic piece 410 has a buckling portion 411. The arc-shaped elastic piece 410 can undergo elastic deformation, so that the buckling portion 411 can be buckled in the buckle groove 130, and the other end of the upper clamping plate 200 can be fixed to the other end of the lower clamping plate 100 through the arc-shaped elastic piece 410. It can be understood that after the multi-cavity injection molding part is placed on the plurality of shaping bumps 110 on the lower clamping plate 100, the operator can rotate the upper clamping plate 200 so that the upper clamping plate 200 approaches the lower clamping plate 100 and the upper clamping plate 200 leans against the multi-cavity injection molding part. Then the operator can swing the arc-shaped elastic piece 410 and make the buckling portion 411 at the lower end of the arc-shaped elastic piece 410 abut against the lower clamping plate 100. Then the operator presses the arc-shaped elastic piece 410 in the direction close to the lower clamping plate 100, so that the arc-shaped elastic piece 410 undergoes elastic deformation, and the buckling portion 411 at the lower end of the arc-shaped elastic piece 410 undergoes elastic deformation and extends into and is buckled in the buckle groove 130. Since the arc-shaped elastic piece 410 is in a deformed state at this time, the arc-shaped elastic piece 410 has a tendency to return to its original state. At this time, the arc-shaped elastic piece 410 can apply a force that makes the upper clamping plate 200 and the lower clamping plate 100 approach each other, so that the other end of the upper clamping plate 200 can be fixed to the other end of the lower clamping plate 100 through the arc-shaped elastic piece 410, and further the upper clamping plate 200 and the plurality of shaping bumps 110 clamp the multi-cavity injection molding part.

[0050] After the multi-cavity injection molding part is naturally cooled, the operator only needs to pull the arc-shaped elastic piece 410 in the direction away from the lower clamping plate 100, so that the buckling portion 411 at the lower end of the arc-shaped elastic piece 410 undergoes elastic deformation and disengages from the buckle groove 130, then the upper clamping plate 200 can be loosened from the multi-cavity injection molding part, and the operator can take the multi-cavity injection molding part away from the lower clamping plate 100.

[0051] Reference Figure 6 and Figure 7The locking assembly 400 further includes a shift block 420, the lower end of which is hinged to the other end of the upper clamping plate 200, the upper end of which is hinged to the middle of the shift block 420, and the upper end of which can swing toward the direction close to the upper clamping plate 200, so that the shift block 420 pulls the arcuate spring sheet 410 to undergo elastic deformation, and the buckle portion 411 buckles in the buckle groove 130, thereby fixing the other end of the upper clamping plate 200 to the other end of the lower clamping plate 100 through the arcuate spring sheet 410. It can be understood that after the multi-cavity injection molded part is placed on the multiple shaping protrusions 110 on the lower clamping plate 100, the operator can rotate the upper clamping plate 200 so that the upper clamping plate 200 is close to the lower clamping plate 100 and the upper clamping plate 200 rests on the multi-cavity injection molded part. Then the operator can swing the shift block 420 to move the upper end of the shift block 420 away from the upper clamping plate 200, and the shift block 420 drives the arc spring piece 410 away from the lower clamping plate 100. Then the operator can align the buckle portion 411 on the lower end of the arc spring with the buckle groove 130 on the lower clamping plate 100 and put it into the buckle groove 130. Then the operator moves the shift block 420 toward the direction close to the upper clamp plate 200, so that the upper end of the shift block 420 swings toward the direction close to the upper clamp plate 200. At this time, the shift block 420 can pull the arc-shaped spring piece 410, so that the arc-shaped spring piece 410 can undergo elastic deformation. At this time, the arc-shaped spring piece 410 can exert a force on the upper clamp plate 200 and the lower clamp plate 100 to approach each other, so that the other end of the upper clamp plate 200 can be fixed to the other end of the lower clamp plate 100 through the arc-shaped spring piece 410, thereby enabling the upper clamp plate 200 and the multiple shaping protrusions 110 to clamp the shaped multi-cavity injection molded parts.

[0052] After the multi-cavity injection molded part is cooled naturally, the operator only needs to move the shift block 420 in the direction away from the upper clamping plate 200, so that the upper end of the shift block 420 swings in the direction away from the upper clamping plate 200. At this time, the shift block 420 relaxes the pulling force on the arc spring piece 410, so that the shift block 420 drives the upper end of the arc spring piece 410 away from the upper end. After the arc spring piece 410 loses the pulling force of the shift block 420, the arc spring piece 410 returns to its original state. At this time, the force between the buckle part 411 and the inner wall of the buckle groove 130 is reduced, and the operator can swing the arc spring piece 410 and remove the buckle part 411 from the buckle groove 130, so that the upper clamping plate 200 can release the multi-cavity injection molded part, and the operator can take the multi-cavity injection molded part away from the lower clamping plate 100.

[0053] refer to Figure 6 and Figure 7 , a paddle 421 is provided at the upper end of the paddle block 420, and the paddle 421 is inclined in a direction away from the upper clamping plate 200. It is understandable that the operator can paddle the paddle block 420 through the paddle 421, so that the operator can swing the paddle block 420, which improves the convenience of the operator's operation. Hinge is a common connection method, which is often connected by rotation through a hinge shaft, and will not be further described here.

[0054] In the embodiment of the present utility model, the upper end of the arc-shaped elastic piece 410 is one end of the arc-shaped elastic piece 410, and the lower end of the arc-shaped elastic piece 410 is the other end of the arc-shaped elastic piece 410. The lower end of the dial block 420 is one end of the dial block 420, and the upper end of the dial block 420 is the other end of the dial block 420.

[0055] Reference Figure 5 , guiding chamfers 111 are provided at the upper ends of multiple shaping bumps 110. It can be understood that the guiding chamfers 111 on the multiple shaping bumps 110 can play a guiding role, enabling the operator to more quickly insert the multiple shaping bumps 110 into multiple cavities of the multi-cavity injection molded part respectively during the process of placing the multi-cavity injection molded part.

[0056] As an embodiment of the present utility model, a holding part (not shown in the figure) is provided on the upper clamping plate 200. It can be understood that the operator can move the lower clamping plate 100 and the upper clamping plate 200 by holding the holding part, improving the convenience of handling the injection molded part shaping device.

[0057] As an embodiment of the present utility model, the injection molded part shaping device further includes a water tank (not shown in the figure) and a lifting driving member (not shown in the figure). The water tank is used to hold water. The lifting driving member is arranged in the water tank, and the output end of the lifting driving member is connected to the lower clamping plate 100. The lifting driving member can drive the lower clamping plate 100 and the upper clamping plate 200 to descend, so that the multi-cavity injection molded part clamped by the upper clamping plate 200 and the multiple shaping bumps 110 is immersed in the water in the water tank. It can be understood that after the upper clamping plate 200 and the multiple shaping bumps 110 clamp the multi-cavity injection molded part, the lifting driving member drives the lower clamping plate 100, the upper clamping plate 200 and the multi-cavity injection molded part to descend, so that the multi-cavity injection molded part can be immersed in water to accelerate the cooling of the multi-cavity injection molded part, so that the operator can more quickly perform subsequent processing on the multi-cavity injection molded part. Specifically, the lifting driving member is a waterproof air cylinder, the cylinder body of the waterproof air cylinder is connected to the inner bottom wall of the water tank, and the piston rod of the waterproof air cylinder is connected to the lower clamping plate 100.
